For jessie the wrong patches got applied. They are based on MR 67, which
didn't get merged in favour of the patch from MR 91.

On a more general notice: This bug has virtually no security impact, it's
hard too see why this change was made for an LTS release to begin with,
but at least wait until it's applied/fixed in unstable before backporting.
